ATOMZER.

Application filed July 22,

To @ZZ @171cm t may concern.'

Be it known that 1, ALBERT AtoNzo Saurer, a citizen of the United States, and resident of New Haven, in the county of 'New Haven and State of Connecticut, have invented certain new and. useful Improvements in Atomizers, of which the following is a specification.

This invention relates generally to atomizers and particularly to an atomizer having a spray distributing nozzle mounted to be rotated in its seat about its main longitudinal axis.

It is an object of this invention to provide an improved atomizer of the general type referred to in which special means are provided for preventingl leakage at the point of juncture of the rotatably mounted nozzle with the reservoir closure or cap. Another object of the invention is to provide an atomizer in which the two-fold action of both pressure and suction are utilized in discharging liquid from the container in order to produce a doubly effective continuous spraying action. Other features of the in vention will be hereinafter referred to.

In the single view comprising the drawing, a preferred form of the invention is shown partly in section and partly in side elevation.

Referring to the drawing, a container or reservoir 1 for the spray liquid is provided with a screw top 2 adapted to be attached to the container and form an air-tight joint therewith. A curved spray nozzle 3 is mounted at one end in the side of the screw top 2 and may be rotated in its seat to cause the discharge end 4 thereof to be presented at an angle to the aXis of rotation and \in any desired lateral direction.

The cap member 2 is provided with an internally threaded bore 5 adapted to engage the correspondingly externally threaded neck 6 of the container 1, and with a flange or skirt member 7 which has supporting engagement with a shoulder 8 on t-he container. A suitable washer 9 is ordinarily kprovided to form an air-tight joint between the container 1 and the container closure member 2.

The cap member 2 is provided with an air inlet passage 1() terminating at one end in a flanged nipple 11 on one side of the cap member, the nipple 11 being formed to receive the end of a section of flexible rubber tubing leading from a rubber bulb or other 1921. Serial No. 485,801,

air compressor. The other end of the angular or i-shaped passage 10 terminates witlr in the bore 5 in communication with the interior of the container 1, as will be seen.

The container top 2 is provided also with two outlet or discharge passages leadingfrom the interior of the container, one of these passages 12 communicating with a downwardly projecting tube 13 which projects into the spray liquid 14 in the container. The other end of the passage 12 flares outwardly into an opening 15, provided in the side of the cap 2 substantially opposite the nipple 11. The other discharge passage 16 in the container top 2 affords a means of communication between the opening 15 in the top 2 and the interior of the container 1.

Communication between the discharge passages 1G and 12 referred to and the spray tube nozzle 3 is brought about in the following manner. The spray tube 3 is of a compound construction and consists of the outer tube 4 and an inner tube 17. The inner end of the inner tube 17 has a tapered formation fitting' the correspondingly flared end of the passage 12, while the outer tube 4 has a tapered construction to fit a conical scat 18 with which the opening 15 in the container top 2 is provided. It will thus be seen that the passage 12 and liquid receivingl tube 13 communicate directly with the inner tube 17. while the outer tube 4 confn'nunicates through the port or passage 1G with the air space within the container 1.

In order to hold the daring ends of the tubes 4 and 17 to their seats a threaded nipple 19 is formed on the side of the top 2 the bore of which is concentric with the openingl 15. An internally threaded collar 2O is formed to engage a flange 21 formed on the tube 4 and to engage the threaded nipple 19. The collar 20 forms a gland or stuffing boi: which can be supplied with a washer or other packing material to form a tight joint and at the same time permit the tubes 4 and 17 to rotate on their concentrically formed seats.

In operation pressure produced in the container 1 above the liquid through the introduction of air through the passage 10 causes liquid to rise in the tube 13 and to flow into the inner spray nozzle tube 17 and to be discharged from the small port 23 in the outer end thereof into engagement with the discharge port 24 in the Cap 4. from which the liquid issues in the form ot a spray. At the same time air pressure in the container l passes through the passage i6 into the outer spray nozzle tube 4', an air stream being thus caused tor produce an aspirating ef'liect on the contents otl the inner tube 17 as the stream tlows past the port-containing terminal ot the inner tube. Itwill thus be seen that both pressure and suction are exerted on the contents oit the inner tube,'pressure b v way ot the tube 'l-3 and suction produced at the discharge extremity ot the tube through the aspirating action ot the air discharged trom the outer tube.

, It will also be seen that the curved torniation ot the spray nozzle and the rotatable mounting oit the nozzle in its seat provides ttor directing the tipy or discharge end ot the nozzle in an upward, downward or other direction bearing an angular relation to the axis ot rotation ot' the nozzle as desired, the air and liquid-tight joint provided by the collar 20 preventing leakage ot spray tluid while permitting the desired rotation of the spray nozzle. lVhile. the nozzle has been described and shown as having a curved formation, it will be clear that a straightlin'e or other Jormation can also be employed, providing` that the discharge end of the nozzle can be directed at an angle to the main axis thereof.

What I claim is:

l; n an atomizer, a container, a` closure top t'or said container, a. passage in said closure top through which air pressure may be forced into said container, a tube supported by said top and extending downwardly into the space for liquid in said container, ai spray nozzle mounted on said closure top and communicating with said downwardly extending tube, said spray nozzle being curved laterally with relation to its longitudinal axis with the tip ot the nozzle positioned in a prolongation ot the axial line passing through the base ot the nozzle and mounted to rotate in its seat in said closure top whereby to change the direction ot projection of the spray, and said spray nozzle being provided with a 'flange Vand n'ieans engageable with said tlange and said closure top for holding said spray nozzle in its seat.

2. In an atomizer, a container, a closure top tor said container, a. passage. in said closure 'top through which air pressure may be 'forced into said container, a. tube supported by said top and extending downwardly into the space for liquid in said container, spray tube mounted on said closure top and communicating with said downwardly 'extending tube, said spray tube being rotatable in its seat and having a curved formation with the tip portion positioned in the axis of rotation of the tube, and a second tube mounted in surrounding relation to said iii-st tube, said second tube being rotatable in its seat and communicating with the interior ot said container wherebyY air pressure discharged tlieretrom at the discharge end of said spray tube aids in 'the discharge ot spray theretrom.
